134 REVIEWS DETECTION OF POISONS. 



this subject we shall close this hasty notice of a book which compares 

 very favourably with the majority of travellers' notes on Canada and 

 the States : 



" Taken as a whole, the inhabitants of both Provinces are attached to England 

 and England's rule ; they receive the news of our reverses with sorrow, and our 

 victories create a burst of enthusiasm from the shores of the St. Lawrence to those 

 of Lake Supei'ior At present every obstacle to Canada's further de- 

 velopment seems to be removed — her constitution has been remodelled within the 

 last few years on an enlarged and liberal basis, — her religious endowments have 



been placed on a permanent footing The sun of prosperity shines 



upon her from the Gulf of St. Lawrence to the distant shores of the Ottawa and 

 the western lakes. She requires only for the future the blessing of God, so freely 



accorded to the nations which honor Him, to make her powerful 



It may be that in future years our mighty nation shall go the way of all that have 

 been before it ; but whether the wise decrees of Providence doom it to flourish or 

 decline, we can still look with confident hope to this noble Colony in the New 

 World, believing that on her enlightened and happy shores, under the influence of 

 beneficent institutions and of a Scriptural faith, the Anglo-Saxon race may reaew 

 the vigor of its youth, and realize in time to come, the brightest hopes which have 

 ever been formed of England, in the New "World."

A Manual of the Detectio7i of Poisons. By Dr. F. J. Otto. Bail- 

 liere. New York, 1857. 



In that invaluable handbook of chemistry, generally known by the 

 name of the Graham-Otto'' s Manual, but which has been so much 

 improved and enlarged in the last edition, that it must rank as an 

 independent work, ^he author. Professor Otto of Brunswick, devotes 

 a large space to the subject of the detection of arsenic in cases requir- 

 ing medico-legal investigation. He has since published this portion of 

 the work separately, adding a description of the modes of detecting 

 the other more commonly occurring poisons, and has added a valuable 

 chapter on the general process to be adopted in those cases where the 

 nature of the poison is unknown or unsuspected, and the chemist is 

 consequently obliged to search for all. 



This little work, which has recently been translated by Dr. Elder- 

 horst of Troy, N. Y., forms, we have no hesitation in saying, one of 

 the most valuable contributions to the literature of practical chemistry 

 that has appeared for many years. Professor Otto is well known as a 

 most accomplished chemist and accurate experimenter, and being in 

 high repute, and constantly employed as an analyst in medico-legal 

 investigations, the various processes recommended in his work have all
